The thunderbolt blade is a recurring sword in Dragon Quest series. It is a very powerful sword and can be used as a tool in battle to call thunder and lightning.


The thunderbolt blade has a curved orange blade much like a scimitar but with a jagged shape meant to evoke the shape of lightning. The entire blade is covered with a golden filigree and the hilt is blue with a golden pommel and a red jewel on its crossguard. The blade also has a white section in the center of its blade which is tapered on both ends and inscribed with runes, as well as a black circle surrounded by triangles closer to the hilt. When the sword is swung in battle, it is accompanied by lightning.


Dragon Quest II[edit]

The thunderbolt blade has an attack bonus of +95 (+80 in the NES version) and it was found in the Cave to Rendarak and served as the Prince of Midenhall's most powerful weapon. It can be sold for a measly 375 gold, but it is not recommended to do so. In addition to melee attacks, the sword could be used during combat as an item which would have the effect of casting Woosh, but with a visual effect of lightning. In various spinoffs, the thunderbolt blade has often appeared as the signature weapon of the Prince of Midenhall.

The thunderbolt blade has an attack bonus of +82 (+85 in the NES version) and can be found in the Cave of the Necrogond. It can be equipped Hero and Warriors, as well as Thieves in the Super Famicom version due to a bug. When used as a tool in battle, it has the same effect as the Boom spell.
